Re: Adding Control files

Less Contention with more controlfiles? No !!!

Even though you may have a million control files (maximum 8), Oracle only reads from the first indicated in the init.ora file.

It will write concurrently in-parallel to all controlfile copies but reads only from one. So if you add more control files, this may actually increase the load on your disk storage through increase write access.
